SPECIFICATION forming part of Letters Patent No. 599,001, dated February15, 1898.

1 Application filed April 17, 1897. Serial No. 632,683. Nomodel.)

To all whom it concern.-

Be it known that I, LOUIS N. LEONARD, a citizen of the United States,residing at Butte,

in the county of Silver Bow and State of Montana, have invented certainnew and use ful Improvements in a Combined Pipe and Monkey Wrench; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theartto which it appertains to make and use the same.

This invention relates to certain improvements in a monkey-wrench, theobject being to combine therewith a removable attachment which willtemporarily make it applicable as a pipe-wrench.

The invention also contemplates the novel construction and arrangementof parts whereby they are made susceptible of rapid adj ustment to nutsof varying sizes.

To these ends the invention comprises certain novel features ofconstruction and arrangement of parts whereby the above and otherimportant advantages are attained and whereby it is made simpler andbetter adapted for the purposes for which it is intended, as willbe-hereinafter fully described, and specifically defined in the appendedclaims.

In the accompanying drawings, Figure 1 represents a perspective view ofa wrench embodying my invention, a portion of the handle being removedto show the construction and arrangement of the parts therein. Fig. 2 isa similar View showing the pipewrench attachment in position thereon,and Fig. 3 is a perspective View of the pipe wrench attachment removed.

Similar reference-numerals designate corresponding parts in all thefigures of the drawings.

1 represents the handle, which is formed of a skeleton frame 2, theupper and lower outer portions of which are designed to follow thecontour of the handle and are so arranged as to provide a longitudinalspace 3 to receive within it the shank at of the movable jaw. Theforward end of the skeleton frame has an enlarged head 5, which servesas the stationary jaw of the wrench.

The extreme end of the shank of the movable jaw is provided with aseries of serrations or teeth 5, and the edge of the skeleton frameadjacent thereto is provided with a series of similar teeth which areintended to engage with each other through the agency of means which Ishall presently describe to prevent the movement of the movable jawafter having been set to the nut. The teeth are normally out ofengagement and will thus permit of the free movement of the movable jaw,so that the wrench may be quickly set to the nut, after which acam-block 6, rotatively secured to the skeleton frame beneath the edgeof the shank of the movable jaw and provided with a suitablefinger-piece to be grasped by the hand, is moved in one direction tocause the end of the shank to rise and bring its teeth into engagementwith the toothed edge of the skeleton frame. The end of the shank isprovided with lateral projections or pins 7 which are designed to movein longitudinal guideways 8, arranged upon either side of the handle, asclearly shown.

Myimproved pipe-wrench'attachment comprises a block 9, having a V-shapedserrated opening 9 to receive the pipe and an extension 9 adapted torest against the side of the shank of the movable jaw. This extension 9*is arranged at one side of the block, and its end is bent to form a lip9, which bears upon the upper edge of the movable jaw, while the upperend of the block bears against the lower edge. Ribs 10 are arranged uponthe block at each side of the V-shaped opening 9, the outer extremitiesof which project beyond the ends of the block and engage the movable andstationary jaw, and in this manner my improved pipe-wrench attachment issecurely held in place. It will thus be seen that my invention providesin a simple and inexpensive manner a combined monkey and pipe wrenchwhich is capable of rapid adjustment to varying-sized nuts and whichprovides a simple and effective. device which may be quickly attached,

so as to convert it into a pipe-wrench. It is but reserve the right tochange and alter the various parts as may be considered to fall withinits spirit and scope.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A wrench, comprisinga handle provided with a groove having teeth orserrations thereon, and a head to form the stationary jaw, a blockhaving a serrated opening and extension and projections at each sidethereof,.a movable jaw arranged upon a shank, adapted to slide withinsaid groove, the end of the shank being provided with teeth orserrations, and a cam-block rotatively secured to said handle bymovement of which the teeth are brought into or out of engagement witheach other, substantially as described.

2. A wrench, comprising a handle provided with a groove having teeth orserrations thereon, and a head to form the stationary jaw, a blockhaving a serrated opening and extension and projections at each sidethereof, a

movable jaw arranged upon a shank, adapted to slide within said groove,the end of the shank being provided with teeth or serrations, andlateral projections or pins adapted to move in grooves in the sides ofthe handle, and a cam-block rotatively secured to said handle bymovement of which the teeth are brought into or out of engagement witheach other, substantially as described.

3. A pipe-wrench attachment, comprising ing witnesses.
